Spring MVC Apache 磁贴：输出中缺少页脚

Question

我现在在 Spring mvc 中尝试学习 apche tiles...但它不起作用...不知道为什么？

Answer 1

你的HTML错了！它在你 "main-content (index.jsp)"!

中有一个结束 <body> 和 <html> 标签

您有自己的模板：classic.jsp 并在 <tiles:insertAttribute name="body" /> 占位符中包含 index.jsp。所以结果 HTML 看起来像，（完整的 index.jsp 将插入占位符！）：

<html>
   <head>
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
      <title>...</title>
   </head>
   <body>
<html>                            <!-- problem starts her -->
  <head>
      <meta http-equiv="Content-Type" content="text/html; charset=ISO8859-1">
      <title>Insert title here</title>
  </head>
  <body>
       <p>index page</p>
   </body>                        <!-- that is the reason for not -->
 </html>                          <!-- having a footer -->
         <br>
        <br>
         <center>
            &copy;IShmam Shahriar
         </center>
     </body>
 </html>

您是否注意到 "close" html 内容 </body> 和 </html> 已经在页脚之前了！ -- 解决方案很简单：从 index.jsp:

中删除所有 header、html 和 body 标签

 <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"   "http://www.w3.org/TR/html4/loose.dtd">

   <p>index page</p>

另外一点：

从配置中删除您的 InternalResourceViewResolver。问题是您有两个视图解析器（内部和 Url/Tiles），您的视图名称（return "index"）很可能由内部视图解析器解析，而不是由 Url/Tiles 解析器解析.

根据Spring Reference, Chapter 18.3.2 Integration Tiles，您只需要：

org.springframework.web.servlet.view.tiles3.TilesConfigurer
org.springframework.web.servlet.view.UrlBasedViewResolver 为 viewClass 配置 TilesView 属性（或使用 org.springframework.web.servlet.view.tiles3.TilesViewResolver - 这是 UrlBasedViewResolver 的已配置子类）
- 你可以有一个org.springframework.web.servlet.view.ResourceBundleViewResolver

示例：

<bean id="tilesConfigurer"
   class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
   <property name="definitions">
       <list>
           <value>/WEB-INF/defs/general.xml</value>
        </list>
    </property>
</bean>

<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver" id="tilesViewResolver">
    <property name="viewClass" value="org.springframework.web.servlet.view.tiles3.TilesView"/>
</bean>
